BACKGROUND Technical Field

The present disclosure relates to a transmission method and device in awireless communication system, and more particularly to a method anddevice for supporting data transmitting on an unlicensed spectrum.

Related Art

In the traditional 3GPP (3rd Generation Partner Project) LTE (Long-termEvolution) system, data transmission can only occur on the licensedspectrum, but with the sharp increase of data transmission traffic,especially in some urban areas, licensed spectrum may be difficult tomeet the demand for data transmission traffic. The communication on theunlicensed spectrum in Release 13 and Release 14 is introduced by thecellular system and used for the transmission of downlink and uplinkdata. In order to ensure compatibility with access technologies on otherunlicensed spectrums, LBT (Listen Before Talk) technology is adopted byLAA (Licensed Assisted Access) of LTE to avoid interference caused bymultiple transmitters occupying the same frequency resource at the sametime.

The uplink transmission in the traditional LTE system is often based onthe grant of the base station. In order to avoid the resourceutilization degradation and delay caused by the frequent use of LBT, theAUL (Autonomous Uplink) transmission is introduced in the unlicensedspectrum in Release 15. In the AUL, the UE (User Equipment) can performuplink transmission independently in the air interface resourcespre-configured by the base station. At present, 5G NR (New Radio AccessTechnology) access technology for unlicensed spectrum is underdiscussion. Large-scale M IMO will be used on a large scale in 5G NR,and unlicensed spectrum grant-free uplink transmission needs to bereconsidered.

SUMMARY

Through the research, the inventors found that how to avoid frequent LBTin the uplink transmission on the unlicensed spectrum of the NR system,effectively realize the sharing of unlicensed spectrum resources bymultiple UEs, and improve the transmission efficiency of unlicensedspectrum is a key problem to be solved.

In response to the above problems, the present disclosure discloses asolution. It should be noted that, in the case of no conflict, thefeatures in the embodiments and the embodiments of the presentdisclosure may be combined with each other arbitrarily.

Embodiment III

Embodiment III shows a schematic diagram of wireless protocolarchitecture of a user plane and a control plane according to thepresent disclosure, as shown in FIG. 3 .

FIG. 3 is a schematic diagram illustrating an embodiment of a wirelessprotocol architecture for a user plane and a control plane, and FIG. 3shows a wireless protocol architecture for the user equipment (UE) andthe base station equipment (gNB or eNB) in three layers: layer 1, layer2 and layer 3. Layer 1 (L1 layer) is the lowest layer and implementsvarious physical layer (PHY) signal processing functions, and layersabove layer 1 belong to higher layers. The L1 layer will be referred toherein as PHY 301. Layer 2 (L2 layer) 305 is above PHY 301 and isresponsible for the link between the UE and the gNB through PHY 301. Inthe user plane, L2 layer 305 comprises a media access control (MAC)sub-layer 302, a radio link control (RLC) sub-layer 303 and a packetdata convergence protocol (PDCP) sub-layer 304, and these sub-layersterminate at the gNB on the network side. Although not illustrated, theUE may have several upper layers above the L2 layer 305, furthercomprising a network layer (e.g. an IP layer) terminated at the P-GW onthe network side and terminated at the other end of the connection (e.g.Application layer at the remote UE, server, etc.). The PDCP sub-layer304 provides multiplexing between different wireless bearers and logicalchannels. The PDCP sublayer 304 also provides header compression forupper layer data packets to reduce wireless transmission overhead, andprovides the security by encrypting data packets, and provides handoffsupport for UEs between gNBs. The RLC sublayer 303 provides segmentationand reassembly of upper layer data packets, retransmission of lostpackets and the reordering of data packets to compensate for thedisordered reception resulted by the hybrid automatic repeat request(HARQ). The MAC sublayer 302 provides multiplexing between the logicaland transport channels. The MAC sublayer 302 is also responsible forallocating various wireless resources (e.g. resource blocks) in one cellbetween UEs. The MAC sublayer 302 is also responsible for HARQoperations. In the control plane, the wireless protocol architecture forthe UE and gNB is substantially the same for the physical layer 301 andthe L2 layer 305, but there is no header compression function for thecontrol plane. The control plane also comprises an RRC (WirelessResource Control) sublayer 306 in Layer 3 (L3 layer). The RRC sublayer306 is responsible for obtaining wireless resources (i.e. wirelessbearers) and configuring the lower layer using RRC signaling between thegNB and the UE.
